A major hurdle to CCSP progress is the program director’s lack of authority to allocate or prioritize funding across participating agencies.

Discovery science and understanding of the climate system are proceeding well, but use of that knowledge to support decision making and to manage risks and opportunities of climate change is proceeding slowly.

Progress in understanding and predicting climate change has improved more at global, continental, and ocean basin scales than at regional and local scales.

Our understanding of the impact of climate changes on human well-being and vulnerabilities is much less developed than our understanding of the natural climate system.

Science quality observation systems have fueled advances in climate change science and applications, but many existing and planned observing systems (satellite missions) have been cancelled, delayed, or degraded, presenting perhaps the single greatest threat to the future success of CCSP.

Progress in communicating CCSP results and engaging stakeholders is inadequate.
